Gardaí have issued an appeal for information about the murder of Paul Cullen, who was shot dead in Dublin on Sunday night.

The father-of-one was shot as he drank with members of his family at The Cabra House pub.

The gunman fired six shots before escaping on a motorbike driven by another man waiting outside.

Garda forensic specialists examined the pub today.

Mr Cullen, 27, who lived across the road on Faussagh Avenue, was with his father and brother at the time of the shooting.

It has emerged that family members threw chairs at the gunman.

Up to 25 people were in the premises at the time and gardaí are appealing for witnesses or anyone with information to contact them.

Mr Cullen, a convicted drug dealer, had only been recently released from prison.

Detectives believe his murder could be connected to a drugs debt.
